In Gipsy Hill (SE19) the split is 63% flats to 37% houses over 3,277 households, and the stock is mainly Victorian.
Because 26% of Gipsy Hill is privately rented and 35% socially rented, a lot of SE19 work is agreed with a landlord or managing agent rather than the person opening the door.
Gipsy Hill substrates run to often with surface conduit — and precast concrete panels and dense blockwork, the pattern behind 3,277 households inside the SE19 neighbourhood. Nothing is drilled until the wall has been sounded, because drilling blind into a panel with reinforcement or a buried cable behind it, as the Gipsy Hill stock goes, which is what a 63% flat share across the ONS neighbourhood covering Gipsy Hill actually produces is the mistake that costs a SE19 customer twice.
Gipsy Hill sits inside the Congestion Charge zone as well as ULEZ, so both are itemised on the quote rather than absorbed into an hourly rate. What shapes the job more is the neighbourhood itself — a hillside of Victorian villas climbing to the ridge below Crystal Palace park — which is why a SE19 quote is not a Lambeth average.
Getting to the door matters as much as the job: some of the steepest gradients in south London, narrow parked-up streets and no off-street loading. Gipsy Hill (Southern) is the nearest station, and two crew and a Luton on most strip-outs; three crew and a tipper where the load is rubble, hardcore or soil and weight rather than volume decides the run.
